Since the outgoingqfilling end is moved laterally of itself outof the tension and take-up device before-the ejected filling carrier has movedany very -substantia'l distance, the continued movement of the latter is unimpededbyfany tension on the fill-' ing end, which is'freeto be "withdrawn from the shuttle eye. This not only permits the filling carrier to fall out'of the path of 'mov-Z ing; parts of the loom," butalso preventsany likelihood, of the filling breaking betvveenthe filling carrier] and shuttle eye; which would be attended'by thedetrimental results previ ouslyvmention'ed. r The foregoing; description of the preferred embodiment of my invention is by no means intended'toglimit the invention to the particw lar :form disclosed It isnoted particularly that'Ifbelie'veI amjthefirstto combine either a tension devicexor a slack take up device in aflooniishuttle With means forlaterally re ihovingthe filling therefrom upon ejectionof thefilling carrier, and I desire to claim this combination broadly,,regardless of the particular form, of "the elements of the combination. 1

Likewise, While the slack take-up device is designed primarily for use in the aforesaid combination it has points of superiority that render it desirable in and of itself, both as a take-up and as a plain first-pick tension. Furthermore, even though the device is thus used by itself it maybe varied in detail Without departing from the spirit of theinvention. 7 i a frombetvveen'the said members.
